Question

which process is a chemical change?
burning a match
boiling water
melting ice
breaking glass

Explanation:

A chemical change results in the formation of new substances. Burning a match involves a chemical reaction (oxidation) that produces new substances like carbon - dioxide, water vapor, and ash. Boiling water, melting ice, and breaking glass are physical changes as they only change the state (in case of water and ice) or physical form (in case of glass) without forming new substances.
